DETAILED DESCRIPTION

An elevated observatory generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 6.

Structure and Relationship of Parts:

Referring to FIG. 1, elevated observatory 10 includes a frame that supports an observatory 14. The frame may have different designs, such as part of a trailer, a skid, the bed of a truck, etc. In the description below, the frame is shown as part of a trailer 12. Observatory 14 is shown to be a type of cabin, however, it will be appreciated that it may be a platform, or may take other forms that would be practical for users such as bird watchers and hunters. Rigid travel guides 16 extend upwardly from trailer 12 and provide a travel path for observatory 14. Trailer 12 has outrigger legs 17 that are extended prior to observatory being elevated. Travel guides 16 have braces 15 to provide additional stability. Observatory 14 is designed to move along the travel path provided by travel guides 16 such that observatory 14 is raised by a pivoting linkage, generally indicated by reference numeral 18, from a transport position shown in FIG. 1 to an observation position shown in FIG. 3. A sliding clamp 19 guides observatory 14 along rigid travel guides 16. Rigid travel guides 16 include axial stops 21 toward the bottom of guides 16, such that, in the transport position shown in FIG. 1, observatory 14 is supported by axial stops 21. Observatory 14 may then be held in place against stops 21 using straps or other locking means to help keep observatory 14 stable during transport.

Pivoting linkage 18 has four collapsible observatory supports 20. Referring to FIG. 4, each collapsible observatory support 20 has a trailer portion 22 (or, more generally, a frame portion) and an observatory portion 24. Trailer portion 22 has a first end 26 pivotally mounted to trailer 12 and a second end 28. Observatory portion 24 has a first end 30 pivotally mounted to observatory 14, a second end 32 pivotally connected to second end 28 of trailer portion 22, and a guide rail 34 secured along the length of each observatory portion 24. There is also a pivoting frame 36 provided on each side of observatory 14. Each pivoting frame 36 is pivotally connected between trailer portion 22 of the two adjacent collapsible observatory supports 20. Each pivoting frame 36 has lifting arms 38 with rail engaging ends 40. Each rail engaging end 40 engages and travels along the corresponding guide rail 34. Referring to FIG. 1, a winch 42 is provided to apply a pulling force to pivot and draw together the two pivoting frames 36, such that observatory supports 20 are straightened, which causes observatory 14 to be raised through the intermediate position shown in FIG. 2 to the observation position shown in FIG. 3. Referring to FIG. 3, observatory 14 is accessible in the observation position by a ladder 45. Referring to FIGS. 1 and 2, ladder 45 folds with pivoting frame 36 to a collapsed state for travel when observatory 14 is in a transport position.

Referring to FIGS. 5 and 6, there is also provided a locking system 44 to lock the pivotal connection 46 between second end 28 of trailer portion 22 and second end 32 of observatory portion 24 to maintain trailer portion 22 and observatory portion 24 in a coaxial relationship. Pivotal connection 46 between second end 28 of trailer portion 22 and second end 32 of observatory portion 24 has an over-center stop position shown in FIG. 6, while a resilient member 48 carried by observatory portion 24 engages trailer portion 22 to maintain the pivot 46 in the over-center position. For additional safety, locking system 44 may be designed such that a release tool 50 is required to release resilient member 48.

Operation:

Referring to FIG. 1, trailer 12 is transported to a desired location with elevated observatory 10 in the transport position. Once properly positioned, outrigger legs 17 are extended to provide additional support to elevated observatory 10 in the observation position shown in FIG. 3, and any straps or other locking means (not shown) used to stabilize elevated observatory 10 are released. Once sufficiently prepared, winch 42 is activated such that a pulling force is applied to winch cables 43, which in turn causes pivoting frames 36 to pivot and be drawn together. It will be understood that other means may also be used to draw pivoting frames 36 together. For example, a separate winch may be used for each cable 43, or winch 42 may be replaced with a motor that turns a screw attached to each pivoting frame (not shown). Further variations will also be apparent to those skilled in the art. As pivoting frames 36 are drawn together, rail engaging ends 40 of lifting arms 38 travel along the corresponding guide rail 34 to exert a lifting force on trailer portion 22. Trailer portion 22 is thus caused to pivot from a substantially horizontal travel position shown in FIG. 1, through the intermediate position shown in FIG. 2 and finally to the substantially vertical observatory supporting position shown in FIG. 3. This in turn lifts observatory portion 24 from a stored positioned shown in FIG. 1, in which it is substantially parallel to trailer portion 22, to an observatory supporting position shown in FIG. 3, in which it is substantially coaxial with trailer portion 22. Referring to FIGS. 5 and 6, as trailer portion 22 and observatory portion 24 reach the substantially coaxial position, resilient member 48 of locking system 44 locks them in place to help ensure that observatory 14 remains in the observation position.

Once it is desired to return observatory 14 to the transport position, some slack is given to cables 43, and locking systems 44 are then released using release tool 50. Referring to FIGS. 2 and 3, once each pivotal connection 46 has been taken out of the over-center position, winch 42 is reversed, such that winch cables 43 are played out, which allows pivoting linkage 18 to return to the position shown in FIG. 1.

In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
